I know everyone has a preference and it also depends on how one uses a camera but just technologically speaking, what is the top, most used digital camera right now by professional wedding photographers and possibly why?

I know Canon and Nikon are the most used, I am looking for an answer with a specific model. Like Nikon D3 or something like that. Something used by professional wedding photographers

Curious :)

Personally, I use Canon 40D and 5DMkII. Its Canon V Nikon really (a bit like PC V Mac). Both will get the job done and it comes down to personal preference.

Though, more important than the camera itself is:

1. The lenses. A poor quality lens on the best camera will result in a poor image.
2. The ability of the photographer. As stated, all the best gear in the world cant make a bad photo a good one.
